Argus4 cameras can be used for spotting a fire in the avionics section of a plane, these are the electronics placed in the belly of the aircraft which service the cockpit. It is extremely hard to find your way through the electronics in a plane and locate the seat of the fire. The Argus4 can enable you to see exactly where the problem is and if the temperature is rising.

The same applies to cockpit fires where a large amount of electronics makes it very difficult to determine the exact location of the overheated area or the fire.
